12. (2v^3 - v + 8) + (-v^3 + v - 3)<br><br> 14. (4h^3 + 3h + 1) - (-5h^3 + 6h - 2)
Lana71 [14]
12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5

14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3

Hope that helps and feel free to ask any questions.

Write 9− 16x⁴ as the product of two factors.
Marysya12 [62]

Answer:

The two factors will be =(3+4x^2)\ and\ (3-4x^2)        

Step-by-step explanation:

We have given the equation 9-16x^4

We know the algebraic equation a^2-b^2=(a+b)(a-b)

As  9-16x^4 can be written as 3^2-(4x^2)^2, as square of 3 is 9 and square of 4x^2 is 16x^4

So 9-16x^4=3^2-(4x^2)^=(3+4x^2)(3-4x^2)

So the two factors will be =(3+4x^2)\ and\ (3-4x^2)

The sum of 16 and a number x is equal to 19
Vladimir79 [104]

Answer:

x = 3

Step-by-step explanation:

We can write the equation as 16 + x = 19

To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.

Hope that helps and have a great day!
